Cement Production HIGHLIGHTS PROCESSES AND TECHNOLOGY STATUS The manufacture of cement is a two-phase process. Clinker is first produced in a kiln system from calcareous limestone, chalk or marl and argillaceous clay or shale materials, with addition, in some cases, of small amounts of corrective materials sand, waste bauxite, iron ore.

Perhaps the type of limestone that many people think of first is the coral reef, which can be seen growing in the worlds warmer, shallow ocean margins. Corals, which are marine animals, gradually add skeletal CaCO 3 to existing reefs and build structures that can be many kilometres long e.g. the Great Barrier Reef off Australia.
